GAS-LAMP.

Patented July 23, 1907.

Original application filed June 22, 1906, Serial No. 322,891. Divided and this application filed June a, 1907. Serial No- 877,652.

To allzvhom it may concern:

vBe it known that I, ALFRED H. HUMPHREY, a citizen of the United'States, residing at the city of New York, gopnty'of New York, and State of N ewYork,

in Gas-Lamps, of which the following is a specification.

This invention relates to'improvements in gas lamps; My invention relates particularly to improvements in valves fer-gas lamps, and is especially designed by me foruse in connection with my improved'gas lamp Patent filed June 22, 1906, Serial No. 322,891, this ap- I plication being a division thereof, although it is adapt- The mainobject of this invention is toprovide in a gas lamp an improved valve for controlling the mainburners and the pilot burner. 1

Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow. I

I accomplish the objects of my invention by the detion. 1

The invention is clearly defined and pointed out in the claims.

A structure embodying thefeatures of my invention is clearly illustrated in the accompanying drawing, forming a part of this specification, in which:

Figure 1 is a view, partially in'vertical section, of a. gas lamp embodying the features of my invention. Fig.

ism takenlooking from the left of Fig. 1. 2,' is an enlarged section through the valve taken on a line corresponding to line 3,-3 of Fig." 2, the valve for the main burner being open and the pilot burner valve being closed. Fig. 4 is a detail section showing the pilot burner valve in its open orflashingposition; Fig. 5 is an enlarged detail section taken on a line corresponding to line 5-5 of Fig. 1, showing structural details of the valve lever.

' In the drawings, the sectional views aretaken lookthe section lines, and similar letters of reference refe to similar parts throughout the several views.

' Referring to the drawings, 1 represents a' gas delivery pipe which is provided with a coupling 2 from which depends the gas delivery pipe extension 3. At the lowerend of this extension 3 is the valve casing 4. The delivery pipe 5 connects the valve casingtothe gas delivery ring-6, the parts being the same'in a general structure as described in my application for patent above referred to.

The chimney 7 is providedwith an outwardly-proat the outer edge.thereof.' Themain burner 10 is arranged through the flange 8 and connected to the gas delivery ring. The mantle 11 is suspended from the mantle holder 12. The chimneyis preferably supportedirom the gas delivery pipe 3, the clip or strap'l3 being arranged to embrace the pipe and being secured thereto by means of suitablecollars, as 14. An outer casing, as 15, is provided, above which is a reflector plate 16, the reflector plate being supported on the supply pipe, as appears from the drawing. I

The globe-supporting band 17 for the globe 20 is pivotally'secured to the depending hinge member 8 on the valve casing by means of a suitable pivot 19. The casing 15 is preferably supported by resting upon the casing band 21, which is mounted on the chimney flange 8. These parts-are substantially the same as thosedescribed in my application for patent above referred to, but it will be readily understood that my improved valve is adapted to use in various other rela- 'tions, and l-show the same in this connection merely to show its utility and application.

The valve casing 4 is provided with the inlet passage 22,:to which the gas delivery pipe 3 is connected to deliver and the discharge passage23, to which the delivery pipe 5 is connected. These passages are connected by the passage 24, which is controlled by the valve 25. Thisvalve is a rotary valve and is provided with two ports 26, arranged 'to be alternately brought intoregister with the passage 24 for opening the valve as it is rotated. On the stem 27 of the valve 25 is pivoted the valve operating lever 28. This lever ispreferably made up of three pieces, 29, 29 and 30, the part or piece 30 being riveted between the pieces 29, whereby they are held properly spaced. Between these pieces 29 I arrange the ratchet 33, which is secured to the valve stem. The valve lever is provided with a pawl 31 adapted to engage the ratchet 33, the pawl being arranged between the lever parts 29. A spring 34 is provided for holding the' pawl in its engaging posi- 'tion.

The ratchet is provided with four-teeth, it being secured on the stem in such a position that one motion of the lever will open the valve and the next close it.

The valve stem is provided with an index '4l, whichiis designed 'to indicate whether the valve is in its open open position in Fig. 2, and by dotted lines in its closed position. A spring dog, 35, adapted to engage the and projecting outwardly therefrom, as clearly appears in Fig. 3. I

"The valve lever is provided with'a rearw'ardly-projecting arm 39, which is adapted toengage the pin 38 and thereby limit the stroke of the lever. This pin also serves as! support for the'return spring 40, one

' or closed position, .it being. shown by full lines in its 100 end of which is secured thereto, the other end being secured to the'outer end of the valve lever, as clearly appears from the drawing.

The valve lever is provided with a projectin g'pin 50,

which is adapted to engagethe lever 42 of the pilot valve on the stroke of the main valve lever. The

. main burner valve lever is adapted to engage the pilot valve lever'when it has partially completed its stroke, thereby opening the pilot valve after the main burner valve is partially open., The pilot valve 43 is threaded into a cup-like valve casing 45, the-casingbeing in turn threaded into the main valve casing 4. This pilot valve casing 45 is provided with a port 46 through its' inner end and a passage 47 through one side tb ereof, to whichthe pilot burner 44 is connected.

The valve 43 is provided with a port 51, which is always open to supply-sufiicient gas to maintain thepilot. The delivery of the gas through this passage is com trolled by means of the screw valve 49, which is thread ed into the valve 43 from its outer end. This enables the accurate adjustment oithe port to regulate theflow of gas to the pilot. When the pilot valve lever 42 is aclevers 28 and 42 are so arrangedthatthe main valve is well as broadly.

opened'or partially opened before the pilot is flashed, allowing the gas'to drive the air from the burnersand the gas delivery pipes beyond the valves. When it is desired to cut off the gas or turn out the light, it is only necessary to again pull on theoperating chain, as 53, and the valves are closed.

My improved valve is very effective iorth'e purpose and is, at the same time, comparatively-simple and economical to produce, I have illustrated and described the same in detail in the form preferred by me on account of structural economy and'convenience in use. I am, however, aware that it is capable of con-- siderable variationin structural details without departing from my invention, and I desire to be understood as claiming the same'specifically, as illustrated, as

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is: I
